I think sharad and sneha know that prem and mukti love each other.It was obvious that sneha knows from todasy episode.BUt also since last few episodes.sharad has beenacting as if he knows that prem and mukti love each other.lets say today only, when prem said NO to mukti todance,sharad could easily c it and he asked mukti to dance and .. and then..when mukti was leaving from the disco, and prem was flirting with the other girl,sharad was doing ishara to prem that mukti is gone.If u did notice,,he was like""ae ..ae.."callign prem.
BTW,hope he is nto guilty...pretty funny.
ANywys..waiting for tommorws episode.
